many, have invented certain new and use ful Improvements in Gas-Producers, of which the follo\\:ing is a specification, ref erence being'had 'to the accompanying drawings.

\\ stirring the fuel at the peripheral portion fof the zone of distillation7 so as to lprevent :the caking of this fuel and the consequent cavitation and burning awny of the wall of the generator at this point winch frequently y"3c arises when, as heretoforelusual, the stirring device is arrangcdnhoVe the fuel, and

operates, mainly upon its central portion.

Other objects of the invention are to provide a stirring device that can he more efwaterlcooled than heretofore, and that docs not project into the depth of the gasification zone, and .consequently becomes injured through burning,

Now in accordance with the present inhe zone of distillation that is (o say, at the level of the fresh .or green fuel. which 1s most hable to cake and to forni masses of considerable size that adh^r to the generator wall and thus interfere with the proper working of the generator; while the construction adopted is moreover such as t0 stir most vigorously that portion of the i0 fuel which otherwise would he most likely t0 become caked and consequently prejudicially to influence the uniform working of the generator, that to say, the portion close to the brirliwork of the producer. .in

5 this construction the stoking arm is arranged in the wall of thegcncrator in such manner as to exercise a leveling and distributing action on the fuel and by this means to obviate the formationof cavities 5U' in the charge, morel particularly in proxiin This application relates/to improvements described with reference, -to the accompanying drawings; whereinw- Figure l is a vertical half section through a producer proridcd With a stirring detice a :ording to the invention, on a plane (aimtainingthe stirring devices; Fig'. 2 is a partial vertical section on a different plane; and Fig. E is a partial horizontal section at the lcvei of the stirring device.

Referriiig nou to the drawings :.-A Water-cooled arin'o attached to the lwall of the rotary upper part 7) of the generator' projects through an aperture o3 in the wall horizontally into the distillation zone thereof. The waterreoled arm a is mounted on e trunnion ai and provided with a 'circuit a2 Patented Muy 19. 1914.

for cooling water supplied from any suitable source. On the trunn'ion a there is keyed an arm c which can be rocked by means of an eccentric (Z. Between the rotary upper portion b of the generator and the remainder of the framework thereof there are j'n'ovided Water seals i and /c with the result that the upper portion Zi and the lower portion comprising the grato n and' around its perijihery7 and running on a circular slightly conical track-g` whereby a propei"rolling movement. between the parts Ji., y is obtained. The rotation of the upper portion /1 of the producer is effected by means of 'worm gear e, c while the lower portion of the producer is'carried by ball hearings y and rotated by worin gear 7. o. That guide wheel i which is situated beneath the stirring arm o is freely rotatable upon a shaftf' to lwhich there i.-: keyed a driving wheel f that meshes into a circular rackrg arranged concentric to track g. To shaft f is also keyed the eccentric (l by means of which the arm c, the trunnion (1 and the stirring deviceny are ropked. this latter device consequently oscillating beM tween its extreme positions indicated respectively by full and broken lines `in Fig. 1.

The operation of the apparatus is as ol-
